According to a new study done by the Washington University of Medicine, researchers have revealed that around 50,000 new cases of Parkinson’s disease have been reported in the US. Parkinson’s is the second most common disease in the US after Alzheimer’; older people get affected from this disease early. The average age of catching the disease is 60.

Researchers are unable to find the cause of the disease, symptoms are slow movement of body, a gait posture, trembling while shaking hands, foot, arm or leg etc.

Researchers studied 20 welders with no Parkinson’s disease, 20 welders who were not welders but had diseases, 20 people with the disease but not welders. Neurologists examined all of them by giving brain PET and MRI scans.

The study revealed that the average level of welders was double the limit of normal blood.

Meanwhile, researchers also said that the changes in welders’ mind were not similar to the damage noticed in people with complete Parkinson’s disease.

The disease has been lacking from biomarkers, which slows down the progress of finding the cure for the disease; the disease is still incurable.
